Webb10 okt. 2024 · We have to add the probabilities of individual events. Four cases will arise. These are (1)one tail and three heads (2)two tails and two heads (3)three tails and one head (4) four tails. So the probability of getting at least one tail = ((0.5)*(0.5)^3 +(0.5)^2*(0.5)^2+ (0.5)^3*(0.5)+ (0.5)^4)=1/4. SO answer will be (C)1/4 WebbIn probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment. It is a mathematical description of a random phenomenon in terms of its sample space and the probabilities of events (subsets of the sample space).. For instance, if X is used to …
